Arctic sea ice extent on September 12, 2009. Daily Arctic sea ice extent on September 12 was 5.10 million square kilometers (1.97 million square miles). The orange line shows the 1979 to 2000 median extent for that day. The black cross indicates the geographic North Pole. - National Snow and Ice Data Center

200 Dead Walruses in Alaska: Global Warming Blamed

The Arctic sea ice has reached the third-lowest level ever recorded, and up to 200 walruses, which appear to be mostly new calves and yearlings, have been reported dead near Icy Cape on the north coast of Alaska – further evidence of global warming’s brutal transformation of the Arctic.
